DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the directions of front, back, left, right, and up and down are based on the directions of the arrows in the drawings. The directions of the arrows are consistent between different drawings. In some drawings, a circuit board CB, which will be described later, is omitted for the purpose of simplifying the illustration.

[0013] Fig. 1 is an external perspective view showing, as viewed from above, a connector module 1 according to one embodiment in a state in which a first connector 10 holding a connection object 40 and a second connector 50 are connected to each other. Fig. 2 is an external perspective view showing, as viewed from above, a connector module 1 according to one embodiment in a state in which the first connector 10 holding a connection object 40 and the second connector 50 are separated from each other. The configurations of the connector module 1 and the first connector 10 according to one embodiment will be mainly described with reference to Figs. 1 and 2.

[0014] The connector module 1 has a first connector 10 and a second connector 50 that are connectable to each other.

[0015] The second connector 50 according to one embodiment is mounted on a circuit board CB. The circuit board CB may be a rigid board or any other circuit board. The second connector 50, together with the first connector 10, electrically connects the connection object 40 inserted into the second connector 50 to the circuit board CB. The second connector 50 is capable of inserting and removing the connection object 40 via the first connector 10, and is connected to the connection object 40 when the connection object 40 is inserted.

[0016] The second connector 50 includes a second insulator 60, a first contact 70a, a second contact 70b, and a second metal member 80. The first contact 70a, the second contact 70b, and the second metal member 80 are attached to the second insulator 60.

[0017] The first connector 10 holds a connection object 40. For example, the first connector 10 receives the connection object 40 that is inserted from the front to the rear, and supports both ends of the connection object 40 in the left-right direction, thereby holding the entire connection object 40.

[0018] The connection object 40 held by the first connector 10 is, for example, an FFC. However, without being limited thereto, the connection object 40 may be any cable as long as it is electrically connected to the circuit board CB via the first connector 10 and the second connector 50. For example, the connection object 40 may be an FPC. The connection object 40 is not limited to the above-mentioned cable and may include any object. For example, the connection object 40 may include a rigid board or any other circuit board.

[0019] The first connector 10 is connectable to the second connector 50 while holding the connection object 40. The first connector 10 has a first insulator 20 that fits into the second insulator 60 in a connected state in which the first connector 10 and the second connector 50 are connected to each other. The first connector 10 has a first metal member 30 attached to the first insulator 20.

[0020] The connection object 40 comes into contact with the second contact 70b when the first insulator 20 and the second insulator 60 are fitted together. The first metal member 30 comes into contact with the first contact 70a when the first insulator 20 and the second insulator 60 are fitted together.

[0021] In the following, for example, the second connector 50 according to one embodiment will be described as a receptacle connector, and the first connector 10 as a plug connector. That is, in a mated state in which the first insulator 20 and the second insulator 60 are mated with each other, the second connector 50 in which the first contacts 70a and the second contacts 70b elastically deform will be described as a receptacle connector, and the first connector 10 holding the connection object 40 will be described as a plug connector. The types of the first connector 10 and the second connector 50 are not limited to these. For example, the second connector 50 may function as a plug connector, and the first connector 10 may function as a receptacle connector.

[0022] In the following description, the connection object 40 is described as being inserted into the second connector 50 in a direction parallel to the circuit board CB on which the second connector 50 is mounted. That is, the connection object 40 is inserted into the second connector 50 along the front-rear direction, as an example. Without being limited thereto, the connection object 40 may be inserted into the second connector 50 in a direction perpendicular to the circuit board CB on which the second connector 50 is mounted. That is, the connection object 40 may be inserted into the second connector 50 along the up-down direction.

[0023] As used below, "the direction in which the contact lines extend" means, for example, the front-rear direction. "The insertion / removal direction" means, for example, the front-rear direction. "The plate thickness direction of the objects to be connected, which is perpendicular to the direction in which the contact lines extend" means, for example, the up-down direction. "The arrangement direction of multiple contact lines, which is perpendicular to the direction in which the contact lines extend" means, for example, the left-right direction. "The tip of the objects to be connected" means, for example, the rear tip of the objects to be connected. "The removal side" means, for example, the front side. "The insertion side" means, for example, the rear side.

[0024] Fig. 3 is an external perspective view showing, from above, the connection object 40 in a state where it is not held by the first connector 10. Fig. 4 is an external perspective view showing, from below, the connection object 40 in a state where it is not held by the first connector 10. The configuration of the connection object 40 held by the first connector 10 will be mainly described with reference to Figs. 3 and 4.

[0025] The connection object 40 has a laminated structure formed by bonding a plurality of thin film materials to each other. The connection object 40 has a reinforcing portion 41 which constitutes the tip portion in the extension direction of the connection object 40, i.e., the insertion / removal direction in which the connection object 40 is inserted and removed, and which is harder than other portions. The connection object 40 has a plurality of contact wires 42 which extend linearly along the insertion / removal direction and which extend to the tip of the reinforcing portion 41. The contact wires 42 are exposed downward at the tip of the connection object 40.

[0026] The connection object 40 has a first ground portion 43 that covers a part of the contact wire 42 with its lower outermost layer on the removal side of the connection object 40. The first ground portion 43 extends from the front to the rear in a flat plate shape and is bent obliquely upward at its tip. The connection object 40 has a second ground portion 44 that covers substantially the entire contact wire 42 with its upper outermost layer. The second ground portion 44 extends from the front to the rear in a flat plate shape and is layered above the reinforcement portion 41 at the tip of the second ground portion 44 while being bent obliquely upward at the front edge of the reinforcement portion 41.

[0027] The connection object 40 has a locked portion 45 formed by cutting out the center portion toward the inside in the left-right direction at an edge portion along the front-rear direction of the tip of the connection object 40 including the reinforcing portion 41. The locked portion 45 is formed on both sides in the left-right direction at the tip of the connection object 40 including the reinforcing portion 41.

[0029] The first insulator 20 is a symmetrical box-shaped member injection-molded from an insulating and heat-resistant synthetic resin material. The first insulator 20 has four outer walls in the top, bottom, left and right directions, and an outer peripheral wall 21 formed in a rectangular shape as a whole. The outer peripheral wall 21 has a ceiling wall 21a, a bottom wall 21b, and a pair of side walls 21c. As shown in FIG. 7, the first insulator 20 has a protruding portion 22 that protrudes from the side wall 21c toward the insertion side of the connection object 40 beyond the ceiling wall 21a and the bottom wall 21b.

[0030] As shown in Fig. 9 to Fig. 11, the first insulator 20 has an insertion portion 23 surrounded in the top, bottom, left and right directions by the outer peripheral wall 21. As shown in Fig. 9, the first insulator 20 has a holding portion 24 recessed inside the protruding portion 22. The first insulator 20 has a locking portion 25 extending from the center of the side wall 21c in the front-to-rear direction to the center of the holding portion 24 in the front-to-rear direction. The locking portion 25 is elastically deformable in the up-to-down direction. As shown in Fig. 10 and Fig. 11, the first insulator 20 has an attachment portion 26 formed along the upper surface of the bottom wall 21b.

[0031] The first metal member 30 is formed by forming a thin plate of any metal material into the shape shown in FIG. 8 using a progressive die (stamping). The first metal member 30 is formed by punching and then bending the plate in the thickness direction. The processing method of the first metal member 30 is not limited to this, and may include, for example, only the punching process. The surface of the first metal member 30 is plated with gold, tin, or the like after forming a base with nickel plating. Plating including nickel plating and surface plating may be applied partially to required areas.

[0032] The first metal member 30 has a first base 31 formed in a plate shape in the front-rear and left-right directions. The first base 31 includes a first portion 31a formed as a flat plate extending in the front-rear and left-right directions, and a second portion 31b bent obliquely upward from the rear edge of the first portion 31a and then extending horizontally again.

[0033] The first metal member 30 has the first base 31, for example, the first extension portion 32a extending rearward from the rear edge of the second portion 31b. The first extension portion 32a bends obliquely upward from the rear edge of the second portion 31b and extends horizontally again at the rear end of the first extension portion 32a. The first extension portion 32a is formed to be wide in the left-right direction from the portion connected to the second portion 31b to the center of the portion extending obliquely upward, and is formed so as to taper at the center. The first extension portion 32a is formed to be narrow in the left-right direction from the rear of the portion extending obliquely upward to the rear end of the first extension portion 32a. The first extension portion 32a is elastically deformable along the up-down direction.

[0034] The first metal member 30 has an opposing portion 32a1 formed on the first extending portion 32a. The opposing portion 32a1 includes substantially the entire rear end portion that extends horizontally in the first extending portion 32a.

[0035] The first metal member 30 has a second extending portion 32b that is bent and extends from the first extending portion 32a and extends along the up-down direction. The second extending portion 32b is continuously connected to the first extending portion 32a with the same left-right width as the rear end portion formed narrow in the first extending portion 32a. The first metal member 30 has a third extending portion 32c that is bent and extends from the second extending portion 32b and extends along the front-rear direction. The third extending portion 32c is continuously connected to the second extending portion 32b with the same left-right width as the second extending portion 32b. The rear end portion formed narrow in the first extending portion 32a, the second extending portion 32b, and the third extending portion 32c are integrally formed in a U-shape when viewed from the side in the left-right direction.

[0036] The extension portions 32, including the first extension portion 32a, the second extension portion 32b, and the third extension portion 32c, are formed in a total of four sets, two sets on the left side and two sets on the right side, in the first metal member 30. The extension portions 32 are arranged in a state spaced apart from each other in the left-right direction. The first extension portion 32a, the second extension portion 32b, and the third extension portion 32c are formed so as to be symmetrical as a whole with respect to a straight line along the front-rear direction.

[0037] The first metal member 30 has a connecting portion 33 that connects a pair of third extending portions 32c adjacent to each other along the left-right direction among the multiple third extending portions 32c. The connecting portion 33 is connected to the front end of the extending portion 32 that is formed so as to extend rearward and then bend back forward at the second extending portion 32b. The connecting portion 33 faces a portion of the second portion 31b that extends obliquely upward and a part of the rear portion of the first portion 31a in the up-down direction. The connecting portion 33 extends from a portion connected to the front end of the third extending portion 32c so as to be bent obliquely upward toward the front, and extends from the top portion of the connecting portion 33 so as to be bent back obliquely downward toward the front.

[0038] The first metal member 30 has a plurality of jumping parts 34 arranged at regular intervals along the left-right direction in the center of the front-rear direction of the first part 31a of the first base part 31. The jumping parts 34 extend obliquely upward in a straight line from the first part 31a and bend upward at the rear end of the jumping parts 34. The jumping parts 34 are formed in a tapered shape so that the width in the left-right direction continuously decreases from the part connected to the first part 31a to the rear end. The entire jumping parts 34 are located above the part cut out in the plate thickness direction in the first part 31a. The jumping parts 34 are elastically deformable along the up-down direction. The jumping parts 34 are not arranged on the same straight line as the extension parts 32, but are formed at a position shifted in the left-right direction.

[0039] The first metal member 30 has locking portions 35 formed on both edge portions of the first portion 31a of the first base portion 31 in the left-right direction.

[0040] 5 to 11, the first connector 10 is assembled by inserting the first metal member 30 from the front side of the first insulator 20 into the first insulator 20 from the front to the rear. The first metal member 30 is held by the first insulator 20 in a state where it is attached to the mounting portion 26 of the first insulator 20.

[0041] In the following, the function of the first connector 10 when the first metal member 30 is attached to the first insulator 20 will be mainly described.

[0042] 6, when the first metal member 30 is attached to the first insulator 20, the locking portions 35 lock onto the inner surfaces of the side walls 21c in the left-right direction. Rear corners of both left-right end edges of the first portion 31a of the first base 31 face the inner surfaces of the side walls 21c facing forward.

[0043] 10 and 11, the first metal member 30 is disposed over substantially the entire lower portion of the first connector 10 along the bottom wall 21b of the first connector 10. The first portion 31a of the first base 31 contacts the upper surface of the bottom wall 21b. The first extension portion 32a extends obliquely upward and rearward from the rear end of the bottom wall 21b. The rear end of the jump-up portion 34 is located inside the insertion portion 23.

[0044] With the first metal member 30 attached to the first insulator 20, the connection object 40 is inserted from the front side of the insertion portion 23 of the first insulator 20 toward the rear. The following mainly describes the function of the first connector 10 when the connection object 40 is inserted into the first insulator 20 and the first connector 10 is attached to the connection object 40.

[0045] 9, when the connection object 40 is inserted into the insertion portion 23 and the first connector 10 is attached to the connection object 40, the holding portion 24 of the first insulator 20 holds the connection object 40 while accommodating the tip of the connection object 40. The locking portion 25 engages with the locked portion 45. As a result, the locking portion 25 functions as a retainer for the connection object 40 from the first connector 10, and prevents the connection object 40 from being unintentionally removed from the first connector 10. As a result, the first connector 10 stably holds the connection object 40.

[0046] 10, the first extending portion 32a extends from the second portion 31b of the first base portion 31 toward the tip of the connection object 40 along the extension direction of the contact wire 42. The facing portion 32a1 formed on the first extending portion 32a faces at least one exposed portion R of the contact wire 42 along the extension direction of the contact wire 42. The facing portion 32a1 extends to the tip of the connection object 40 along the exposed portion R of the contact wire 42 located up to the tip of the connection object 40. The facing portion 32a1 continuously covers the entire central portion and rear portion of the exposed portion R of the contact wire 42 from below all the way to the rear tip.

[0047] 7, the facing portion 32a1 contacts the exposed portion R of at least one contact line 42. One facing portion 32a1 contacts two adjacent contact lines 42 along the left-right direction. The first extending portion 32a contacts the connection object 40 via the facing portion 32a1 in a state where it is elastically deformed downward.

[0048] Of the multiple facing portions 32a1, a pair of facing portions 32a1 adjacent to each other in the left-right direction are positioned so as to sandwich the exposed portion R of at least one of the contact wires 42 in the arrangement direction of the multiple contact wires 42 perpendicular to the extension direction of the contact wires 42. For example, the pair of adjacent facing portions 32a1 are positioned so as to sandwich the exposed portion R of the multiple contact wires 42 in the arrangement direction of the multiple contact wires 42.

[0049] 10, the second extending portion 32b, which is bent and extends from the facing portion 32a1, faces the tip of the connection object 40 along the plate thickness direction of the connection object 40, which is perpendicular to the extending direction of the contact line 42. The second extending portion 32b is spaced apart from the tip of the connection object 40 in the front-rear direction and covers a part of the tip of the connection object 40 from the rear. The facing portion 32a1 and the second extending portion 32b integrally cover a part of the tip of the connection object 40 from two directions, namely below and behind.

[0050] The third extending portion 32c bends and extends from the second extending portion 32b, and faces the connection object 40 along the extending direction of the contact wire 42. The third extending portion 32c is spaced apart from the second ground portion 44 of the connection object 40 in the up-down direction, and covers a part of the second ground portion 44 from above. The facing portion 32a1, the second extending portion 32b, and the third extending portion 32c integrally cover a part of the tip of the connection object 40 from three directions, namely, below, behind, and above.

[0051] The first extending portion 32a faces a first ground portion 43 of the connection object 40, which covers the multiple contact wires 42, along the extending direction of the contact wires 42. For example, a portion of the first extending portion 32a that is located forward from the center of the portion extending diagonally upward faces a portion of the first ground portion 43 that is bent diagonally upward and is spaced apart in the up-down direction.

[0052] The second portion 31b of the first base portion 31 extends rearward from the first portion 31a and contacts the first ground portion 43. The second portion 31b is located on the opposite side of the tip of the connection object 40 from the first extending portion 32a. The second portion 31b is located on the same side of the connection object 40 as the first extending portion 32a in the up-down direction.

[0053] 8, the connecting portion 33 connects the multiple third extending portions 32c along the arrangement direction of the multiple contact wires 42 that is perpendicular to the extension direction of the contact wires 42. For example, the connecting portion 33 connects a pair of the multiple third extending portions 32c that are adjacent to each other along the left-right direction among the multiple third extending portions 32c along the left-right direction. One connecting portion 33 connects the two sets of extending portions 32 on the left side along the left-right direction. The other connecting portion 33 connects the two sets of extending portions 32 on the right side along the left-right direction.

[0054] As shown in FIG. 10, the rear of the first portion 31a, the second portion 31b, the extension portion 32, and the connecting portion 33 integrally cover a portion of the tip of the connection object 40 including the reinforcing portion 41 from three directions: below, behind, and above.

[0055] 11, the jumping part 34 extends rearward from the first base part 31 and contacts the first ground part 43. The jumping part 34 is located on the opposite side of the tip of the connection object 40 from the first extending part 32a. The jumping part 34 contacts the connection object 40 in a state where it is elastically deformed downward.

[0056] The jumping part 34 is located on the same side as the first extending part 32a with respect to the connection object 40 in the up-down direction. The jumping part 34 is not disposed linearly with respect to the first extending part 32a along the extension direction of the contact line 42, but is formed at a position offset in the left-right direction.

[0057] Fig. 12 is an external perspective view of the second connector 50 alone in Fig. 1 as viewed from above from the rear. Fig. 13 is an external perspective view of the second connector 50 alone in Fig. 1 as viewed from above from the front. Fig. 14 is an exploded perspective view of the second connector 50 alone in Fig. 13. The configuration of the second connector 50 according to one embodiment will be described with reference mainly to Figs. 12 to 14.

[0058] The second connector 50 is assembled, for example, by the following method. That is, the first contact 70a and the second contact 70b are press-fitted into the second insulator 60 from the rear of the second insulator 60. The second metal member 80 is press-fitted into the second insulator 60 from above so as to cover the entire second insulator 60. Referring to FIG. 1, the second connector 50 is mounted on a circuit board CB. The second connector 50 electrically connects the connection target 40 and the circuit board CB via the first contact 70a and the second contact 70b.

[0059] As shown in Fig. 14, the second insulator 60 is a symmetrical box-shaped member that is injection molded from an insulating and heat-resistant synthetic resin material. The second insulator 60 may be formed asymmetrically. The second insulator 60 has four outer walls in the top, bottom, left and right directions, and has an outer peripheral wall 61 that is formed in a rectangular shape as a whole. The outer peripheral wall 61 has a ceiling wall 61a, a bottom wall 61b, and a pair of side walls 61c.

[0060] As shown in Fig. 12, the second insulator 60 has a rear wall 62 formed continuously with the ceiling wall 61a and a pair of side walls 61c. As shown in Fig. 13 and Fig. 14, the second insulator 60 has an insertion portion 63 surrounded in the top, bottom, left and right directions by an outer peripheral wall 61. The front side of the insertion portion 63 is largely open due to an opening in the second insulator 60. On the other hand, the rear side of the insertion portion 63 is closed by the rear wall 62.

[0061] 14, the second insulator 60 has a first hole 64a formed at both left and right ends of the ceiling wall 61a and penetrating the ceiling wall 61a from the upper surface of the ceiling wall 61a to the insertion portion 63.

[0062] The second insulator 60 has a plurality of second holes 64b arranged at a distance from each other in the left-right direction at the front edge of the top wall 61a. As shown in Fig. 12, the second insulator 60 has a plurality of third holes 64c arranged at a distance from each other in the left-right direction at the upper edge of the rear wall 62.

[0063] 13 and 14, the second insulator 60 has a plurality of contact mounting grooves 65 recessed to extend in the front-rear direction from the outer surface of the rear wall 62 to the inside of the insertion portion 63. The plurality of contact mounting grooves 65 are arranged in the left-right direction at predetermined intervals from each other. The contact mounting grooves 65 include a first contact mounting groove 65a and a second contact mounting groove 65b. The first contact mounting groove 65a is recessed at a position that matches the number and mounting positions of the first contacts 70a shown in FIG. 14. The second contact mounting groove 65b is recessed at a position that matches the number and mounting positions of the second contacts 70b shown in FIG. 14.

[0064] The first contacts 70a are formed by stamping a thin plate of spring-elastic copper alloy or Corson copper alloy containing phosphor bronze, beryllium copper, or titanium copper into the shape shown in FIG. 14. The first contacts 70a are formed only by punching. The processing method of the first contacts 70a is not limited to this, and may include a step of bending the plate in the thickness direction after punching. The surface of the first contacts 70a is plated with gold or tin after forming a base with nickel plating. A total of eight first contacts 70a are arranged in the second connector 50, four on the left side and four on the right side.

[0065] The first contact 70a has a rectangular locking portion 71a with a protrusion on the upper edge. The first contact 70a has a mounting portion 72a that extends backward in an L-shape from the lower end of the locking portion 71a. The first contact 70a has a first contact portion 73a that extends forward while bending from the front end of the locking portion 71a.

[0066] The second contact 70b is formed by forming a thin plate of spring-elastic copper alloy or Corson copper alloy containing phosphor bronze, beryllium copper, or titanium copper into the shape shown in FIG. 14 using a progressive die (stamping). The second contact 70b is formed only by punching. The processing method of the second contact 70b is not limited to this, and may include, for example, a step of bending the plate in the thickness direction after punching. The surface of the second contact 70b is plated with gold, tin, or the like after forming a base with nickel plating. A plurality of second contacts 70b are arranged in the second connector 50 at intervals from each other in the left-right direction.

[0067] The second contact 70b has a rectangular locking portion 71b with a protrusion on the upper edge. The second contact 70b has a mounting portion 72b that extends backward in an L-shape from the lower end of the locking portion 71b. The second contact 70b has a second contact portion 73b that extends forward while bending from the front end of the locking portion 71b.

[0068] The second metal member 80 is formed by forming a thin plate of any metal material into the shape shown in Fig. 14 using a progressive die (stamping). The second metal member 80 is formed by punching and then bending the plate in the thickness direction. The processing method of the second metal member 80 is not limited to this, and may include, for example, only the punching process.

[0069] The second metal member 80 has a plate-shaped second base portion 81 that constitutes an upper portion of the second metal member 80. As shown in Fig. 12, the second metal member 80 has a third base portion 82 that extends downward from the second base portion 81 while bending.

[0070] 14, the second metal member 80 has a plurality of first claws 83 extending in a crank shape from the front edge of the second base portion 81. The plurality of first claws 83 are arranged at a distance from one another in the left-right direction. The first claws 83 engage with the second hole portions 64b of the second insulator 60 when the second metal member 80 is attached to the second insulator 60.

[0071] 12 and 14, the second metal member 80 has a plurality of second claws 84 that protrude forward in a folded-back manner from the lower edge of the third base portion 82. The second claws 84 are arranged at a distance from one another in the left-right direction. When the second metal member 80 is attached to the second insulator 60, the second claws 84 engage with the third hole portions 64c of the second insulator 60 shown in FIG.

[0072] The second metal member 80 has a first locking portion 85a extending downward in a U-shape from both ends in the left-right direction at the rear edge of the second base portion 81. The first locking portion 85a is locked to the rear wall 62 of the second insulator 60 shown in FIG. 12 when the second metal member 80 is attached to the second insulator 60. The second metal member 80 has a second locking portion 85b extending downward while bending from the edge of the left-right direction of the second base portion 81. The second locking portion 85b is locked to the side wall 61c of the second insulator 60 shown in FIG. 13 when the second metal member 80 is attached to the second insulator 60. The second metal member 80 has a mounting portion 86 extending outward in the left-right direction while bending from the front end of the lower edge of the second locking portion 85b.

[0073] 12 and 14, the second metal member 80 has engagement portions 87 that extend linearly obliquely downward from both left and right ends of the second base portion 81. The engagement portions 87 are elastically deformable in the up-down direction.

[0074] Referring to FIG. 1, the second connector 50 is mounted on a circuit formation surface formed on the upper surface of the circuit board CB. More specifically, the mounting portion 72a of the first contact 70a is placed on the solder paste applied to the pattern on the circuit board CB. The mounting portion 72b of the second contact 70b is placed on the solder paste applied to the pattern on the circuit board CB. The mounting portion 86 of the second metal member 80 is placed on the solder paste applied to the pattern on the circuit board CB. The mounting portions 72a, 72b, and 86 are soldered to the above-mentioned patterns by heating and melting each solder paste in a reflow furnace or the like. As a result, the mounting of the second connector 50 on the circuit board CB is completed. On the circuit formation surface of the circuit board CB, electronic components other than the second connector 50, such as a CPU (Central Processing Unit), a controller, or a memory, are mounted.

[0075] Fig. 15 is a cross-sectional view taken along the line XV-XV in Fig. 12. Fig. 16 is a cross-sectional view taken along the line XVI-XVI in Fig. 12. Fig. 17 is a cross-sectional view taken along the line XVII-XVII in Fig. 12. The following mainly describes the function of the connector module 1 in a connected state in which the first connector 10 is connected to the second connector 50 while holding the connection object 40.

[0076] 9 and 15, the protrusion 22 of the first insulator 20 is received in the insertion portion 63 of the second insulator 60. The engagement portion 87 of the second metal member 80 reaches the inside of the insertion portion 63 through the first hole portion 64a of the second insulator 60. When the first connector 10 and the second connector 50 are fitted together, the first insulator 20 and the second insulator 60 are fitted together. In this fitted state, the holding portion 24 of the first insulator 20 and the engagement portion 87 of the second metal member 80 are engaged with each other.

[0077] 16, the first contact 70a is attached to the second insulator 60 by being engaged with the first contact attachment groove 65a of the second insulator 60. The first contact portion 73a of the first contact 70a contacts the first metal member 30. More specifically, the first contact portion 73a contacts the first extension portion 32a of the first metal member 30. At this time, the first contact portion 73a elastically deforms downward. The first contact portion 73a is located on the same side as the first extension portion 32a with respect to the connection object 40 in the up-down direction.

[0078] As described above, the first contact 70a comes into contact with the first metal member 30 of the first connector 10. The first contact 70a is used for grounding, for example.

[0079] 17, the second contact 70b is attached to the second insulator 60 by being engaged with the second contact attachment groove 65b of the second insulator 60. The second contact portion 73b of the second contact 70b contacts the contact wire 42 of the connection object 40. At this time, the second contact portion 73b elastically deforms downward. The second contact portion 73b is located on the same side as the first extension portion 32a with respect to the connection object 40 in the up-down direction.

[0080] As described above, the second contact 70b directly contacts the contact wire 42 of the connection object 40. The second contact 70b is used for signals, for example.

[0081] In the following, the effects of the first connector 10 will be mainly described, but the same description also applies to the connector module 1 having the first connector 10.

[0082] According to the first connector 10 of the embodiment described above, it is possible to improve the transmission characteristics in signal transmission. Since the first metal member 30 has the facing portion 32a1 facing the exposed portion R of the contact wire 42, the facing portion 32a1 is close to the corresponding portion of the contact wire 42. As a result, the characteristic impedance of the contact wire 42 is reduced in the vicinity of the facing portion 32a1. More specifically, by bringing the electrically conductive facing portion 32a1 close to the contact wire 42 across a space, an effect similar to that of a capacitor can be obtained between them. If the capacitance is C, the characteristic impedance Z at this time depends on the capacitance C. For example, the characteristic impedance Z is inversely proportional to the square root of the capacitance C, or is inversely proportional to the capacitance C. Therefore, the characteristic impedance is reduced by narrowing the interval between the capacitors and increasing the capacitance C. In this way, the transmission characteristics in signal transmission are improved by adjusting the value of the characteristic impedance to approach the ideal value.

[0083] The first metal member 30 has the second extending portion 32b that bends and extends from the facing portion 32a1 and faces the tip of the connection object 40 along the plate thickness direction of the connection object 40, so that the tip of the connection object 40 can be protected from the outside by the facing portion 32a1 and the second extending portion 32b of the first metal member 30. For example, the facing portion 32a1 and the second extending portion 32b cover the tip of the connection object 40 from below and from behind, respectively, so that it is possible to prevent the arm of an assembly device, other electronic components, the circuit board CB, and the like from directly contacting the tip of the connection object 40 from these directions. Therefore, it is possible to prevent the connection object 40 from bending in the vertical direction due to contact from the outside at the tip of the connection object 40. As a result, the robustness of the first connector 10 when holding the connection object 40 is improved.

[0084] In addition, by having the second extending portion 32b in the first metal member 30, it is possible to suppress the curling of the first metal member 30 that occurs when the first extending portion 32a is included without the second extending portion 32b. For example, in FIG. 10, when the extending portion 32 is formed only up to the first extending portion 32a, the arm of the assembly device, other electronic components, the circuit board CB, etc. come into contact with the contact portion between the contact wire 42 of the connection object 40 and the facing portion 32a1, and the first metal member 30 is likely to curl downward at the first extending portion 32a. By having the second extending portion 32b in the first metal member 30, such curling of the first metal member 30 is suppressed. Therefore, the robustness of the first connector 10 itself that holds the connection object 40 is also improved.

[0085] In the first connector 10, the facing portion 32a1 of the first metal member 30 comes into contact with the exposed portion R of the contact wire 42 of the connection object 40, so that some of the multiple contact wires 42 of the connection object 40 can be electrically connected to the first metal member 30. Therefore, the contact wire 42 and the first metal member 30 function stably as a single ground. Since some of the multiple contact wires 42 function stably as a ground, crosstalk between the other multiple contact wires 42 through which electrical signals are transmitted is suppressed.

[0086] In addition, in the first connector 10, the second portion 31b of the first metal member 30 comes into contact with the first ground portion 43 of the connection object 40, so that some of the multiple contact wires 42 in the connection object 40 can be electrically connected to the first ground portion 43 via the first metal member 30. Therefore, the contact wires 42, the first metal member 30, and the first ground portion 43 function more stably as a single ground. Since some of the multiple contact wires 42 function more stably as a ground, crosstalk between the other multiple contact wires 42 through which electrical signals are transmitted is further suppressed.

[0087] When one first extending portion 32a contacts multiple contact wires 42, crosstalk is suppressed compared to when only one contact wire 42 is contacted. When one first extending portion 32a contacts multiple contact wires 42, contact between the first metal member 30 and the contact wire 42 of the connection object 40 is more reliable. The robustness of the contact between the first metal member 30 and the contact wire 42 is improved. As a result, the contact wire 42, the first metal member 30, and the first ground portion 43 function more stably as a single ground. This further suppresses crosstalk between the other multiple contact wires 42 through which electrical signals are transmitted.

[0088] By bringing the first metal member 30 into contact with the contact wire 42 and the first ground portion 43, it is possible to extend the function of the first ground portion 43 of the connection object 40 to the contact wire 42. For example, the contact wire 42, the first metal member 30, and the first ground portion 43 function as one shield.

[0089] Since the pair of opposing portions 32a1 are positioned so as to sandwich the exposed portion R of at least one contact wire 42 in the arrangement direction of the contact wires 42, the portion of the tip of the connection object 40 that can be protected from the outside by the opposing portion 32a1 and the second extending portion 32b increases. Therefore, it is possible to further prevent the connection object 40 from bending in the vertical direction or the first metal member 30 from rolling downward due to contact from the outside at the tip of the connection object 40. As a result, the robustness of the first connector 10 when holding the connection object 40 is further improved.

[0090] The first extending portion 32a faces the first ground portion 43 of the connection object 40, which covers the multiple contact wires 42, along the extending direction of the contact wires 42, and is therefore close to the corresponding portion of the first ground portion 43. This reduces the characteristic impedance of the first ground portion 43 in the vicinity of the first extending portion 32a. This further improves the transmission characteristics in signal transmission.

[0091] Since the opposing portion 32a1 extends along the exposed portion R located at the tip of the connection object 40, the transmission characteristics in the above-mentioned signal transmission and the robustness when the first connector 10 holds the connection object 40 are further improved.

[0092] The first metal member 30 has the third extending portion 32c that is bent and extends from the second extending portion 32b and faces the connection object 40 along the extending direction of the contact line 42, so that the tip of the connection object 40 can be protected from the outside by the facing portion 32a1, the second extending portion 32b, and the third extending portion 32c of the first metal member 30. For example, the facing portion 32a1, the second extending portion 32b, and the third extending portion 32c cover the tip of the connection object 40 from below, behind, and above, respectively, so that it is possible to prevent the arm of the assembly device, other electronic components, the circuit board CB, and the like from directly contacting the tip of the connection object 40 from these directions. Therefore, it is possible to further prevent the connection object 40 from bending in the vertical direction or the first metal member 30 from rolling down due to contact from the outside at the tip of the connection object 40. As a result, the robustness of the first connector 10 when holding the connection object 40 is further improved.

[0093] The third extending portion 32c covers the tip of the connection object 40 from above, and thus it is possible to directly suppress the connection object 40 from bending upward. Therefore, the robustness of the first connector 10 when holding the connection object 40 is further improved.

[0094] Since the first metal member 30 has the connecting portion 33 that connects the third extension portions 32c along the arrangement direction of the contact wires 42, the adjacent extension portions 32 can be firmly connected along the arrangement direction of the contact wires 42. Therefore, compared with a case where the third extension portion 32c included in the extension portion 32 is formed as a free end without being connected by the connecting portion 33, the strength of the one extension portion 32, the connecting portion 33, and the other extension portion 32 as a whole can be improved. This makes it possible to further suppress bending of the connection object 40 in the vertical direction or rolling down of the first metal member 30 due to contact from the outside at the tip of the connection object 40. As a result, the robustness of the first connector 10 when holding the connection object 40 is further improved.

[0095] The one third extending portion 32c, the coupling portion 33, and the other third extending portion 32c as a whole integrally cover the tip portion of the connection object 40 from above, so that it is possible to directly suppress the connection object 40 from bending upward. Therefore, the robustness of the first connector 10 when holding the connection object 40 is further improved.

[0096] The one third extending portion 32c, the coupling portion 33, and the other third extending portion 32c as a whole integrally cover the tip portion of the connection object 40 from above, thereby suppressing the outflow and inflow of noise to the electric signal. For example, the outflow of electromagnetic noise generated from the electric signal transmitted by the contact wire 42 to the outside of the first connector 10 is suppressed. For example, the inflow of electromagnetic noise generated from another electronic component arranged on the circuit board CB into the inside of the first connector 10 is suppressed.

[0097] The first extension portion 32a is elastically deformable, and contacts the connection object 40 in an elastically deformed state, thereby improving contact reliability. For example, even if the connection object 40 vibrates, the first extension portion 32a elastically deforms, so that contact with the connection object 40 is more reliably maintained. In addition, when the connection object 40 is inserted into the first connector 10, the tolerance of the thickness in the vertical direction of the connection object 40 can be absorbed. Therefore, the workability when inserting and holding the connection object 40 in the first connector 10 is improved. In addition, the first connector 10 can improve the contact reliability with the connection object 40 compared to a case where the first extension portion 32a does not elastically deform. As a result, the assemblyability between the first connector 10 and the connection object 40 is improved. As a result, the productivity is improved when producing an electronic device by electrically connecting the connection object 40 and the circuit board CB via the connector module 1.

[0098] The first contact 70a of the second connector 50 comes into contact with the first metal member 30, thereby increasing the number of contact points serving as ground. That is, the first contact 70a of the second connector 50 can also be electrically connected to the first ground portion 43 via the first metal member 30. Therefore, the first contact 70a, the contact wire 42, the first metal member 30, and the first ground portion 43 function stably as one ground. As a result, crosstalk between the other multiple contact wires 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.

[0099] The first contacts 70a are in indirect contact with the multiple contact wires 42 via the first metal member 30. This also makes it possible to easily change the spacing between the first contacts 70a in the left-right direction.

[0100] The second metal member 80 is press-fitted into the second insulator 60 so as to cover the entire second insulator 60 from above, thereby suppressing the outflow and inflow of noise to the electrical signal. For example, the outflow of electromagnetic noise generated from the electrical signal transmitted by the second contact 70b to the outside of the second connector 50 is suppressed. For example, the inflow of electromagnetic noise generated from another electronic component arranged on the circuit board CB into the inside of the second connector 50 is suppressed.

[0101] It is obvious to those skilled in the art that the present disclosure can be realized in other specific forms other than the above-described embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above description is illustrative and not limiting. The scope of the disclosure is defined by the appended claims, not by the above description. Any modifications within the scope of the equivalents of all modifications are intended to be included therein.

[0102] For example, the shape, arrangement, orientation, number, etc. of each of the above-mentioned components are not limited to the above description and the contents illustrated in the drawings. The shape, arrangement, orientation, number, etc. of each of the components may be arbitrarily configured as long as the function can be realized.

[0103] The method of assembling the first connector 10 described above is not limited to the above description. The method of assembling the first connector 10 may be any method as long as it allows the first connector 10 to be assembled in such a way that each function can be exerted. For example, the first metal member 30 may be molded integrally with the first insulator 20 by insert molding instead of press-fitting.

[0104] The method of assembling the second connector 50 described above is not limited to the above description. The method of assembling the second connector 50 may be any method as long as the second connector 50 can be assembled in such a way that each of the functions can be exerted. For example, at least one of the first contact 70a, the second contact 70b, and the second metal member 80 may be molded integrally with the second insulator 60 by insert molding instead of press-fitting.

[0105] In the above embodiment, the facing portion 32a1 is described as being in contact with the exposed portion R of the contact wire 42, but this is not limited thereto. The facing portion 32a1 does not have to be in contact with the exposed portion R of the contact wire 42. The facing portion 32a1 may be disposed so as to be spaced apart from the contact wire 42 at a position close to the contact wire 42.

[0106] In the above embodiment, the first metal member 30 has been described as having a plurality of facing portions 32a1, but is not limited thereto. The first metal member 30 may have only one facing portion 32a1. The facing portion 32a1 may be formed at any position on the first metal member 30 as long as it is formed on the first extension portion 32a and faces at least one exposed portion R of the contact wire 42 along the extension direction of the contact wire 42.

[0107] In the above embodiment, the facing portion 32a1 has been described as extending along the exposed portion R located up to the tip of the connection object 40, but is not limited thereto. The exposed portion R of the contact wire 42 of the connection object 40 does not have to be located up to the tip of the connection object 40. For example, the facing portion 32a1 may extend along the exposed portion R located forward of the tip of the connection object 40, and extend to the tip of the connection object 40.

[0108] In the above embodiment, the width of the second extending portion 32b is the same as the width of the facing portion 32a1 in the arrangement direction of the contact wires 42, but is not limited thereto. The width of the second extending portion 32b may be larger than the width of the facing portion 32a1 in the arrangement direction of the contact wires 42.

[0109] In the above embodiment, the first metal member 30 has been described as having the third extending portion 32c that bends and extends from the second extending portion 32b and faces the connection object 40 along the extending direction of the contact wire 42, but is not limited thereto. The first metal member 30 does not necessarily have to have the third extending portion 32c. The extending portion 32 of the first metal member 30 may be composed of only the first extending portion 32a and the second extending portion 32b.

[0110] In the above embodiment, the third extension portion 32c is described as being continuously formed without any holes, but is not limited thereto. The third extension portion 32c may have any number of holes at any positions. This makes it possible to easily spray a plating solution onto the surface of the facing portion 32a1 when plating the surface of the facing portion 32a1.

[0111] In the above embodiment, the first metal member 30 has been described as having the connecting portion 33 that connects the multiple third extension portions 32c along the arrangement direction of the multiple contact wires 42, but is not limited thereto. The first metal member 30 may be formed so that the third extension portions 32c are independent of each other without having the connecting portion 33. Conversely, the connecting portion 33 of the first metal member 30 may connect all the third extension portions 32c along the arrangement direction of the multiple contact wires 42. In the first metal member 30, all the extension portions 32 arranged in the left-right direction and the connecting portion 33 may be formed integrally.

[0112] In the above embodiment, the width of the third extension portion 32c is the same as the width of the facing portion 32a1 in the arrangement direction of the multiple contact wires 42, but is not limited thereto. The width of the third extension portion 32c may be larger than the width of the facing portion 32a1 in the arrangement direction of the multiple contact wires 42.

[0113] In the above embodiment, the first extending portion 32a is described as being elastically deformable, but the present invention is not limited to this. The first extending portion 32a does not have to be elastically deformable.

[0114] In the above embodiment, it has been described that one first extending portion 32a contacts two adjacent contact wires 42, but this is not limited thereto. One first extending portion 32a may contact three or more contact wires 42, or may contact only one contact wire 42.

[0115] In the above embodiment, the first extending portion 32a, the second extending portion 32b, and the third extending portion 32c are formed so as to be symmetrical as a whole with respect to a straight line along the front-rear direction, but this is not limited thereto. The first extending portion 32a, the second extending portion 32b, and the third extending portion 32c may be formed so as to be asymmetrical as a whole with respect to a straight line along the front-rear direction, as long as the facing portion 32a1 of the first extending portion 32a is located at the same position as the left-right position of the ground contact wire 42.

[0116] In the above embodiment, as shown in Fig. 8, the extension portion 32 including the first extension portion 32a, the second extension portion 32b, and the third extension portion 32c is formed in a total of four sets, two sets on the left side and two sets on the right side, in the first metal member 30, but this is not limited to the above. The extension portions 32 may be formed in any number at any positions other than the positions shown in Fig. 8.

[0117] In the above embodiment, the first contact 70a has been described as having the first contact portion 73a that contacts the first metal member 30, but is not limited thereto. The first contact 70a may contact, for example, the contact wire 42 of the connection object 40 without contacting the first metal member 30. In this case, the first contact 70a may be used for signals rather than for ground.

[0118] In the above embodiment, as shown in Fig. 14, two first contacts 70a are arranged between multiple second contacts 70b, but this is not limited to the above. The first contacts 70a and the second contacts 70b may be arranged in any manner. For example, one first contact 70a may be arranged between multiple second contacts 70b, or the first contacts 70a and the second contacts 70b may be arranged alternately.

[0119] The first connector 10 or the connector module 1 as described above is mounted on an electronic device. The electronic device includes any information device such as a personal computer, a game machine, a copier, a printer, a facsimile, and a multifunction device. The electronic device includes any audiovisual device such as a liquid crystal television, a recorder, a camera, and a headphone. Without being limited thereto, the electronic device may include any in-vehicle device such as a camera, a radar, a drive recorder, and an engine control unit. The electronic device may include any in-vehicle device used in an in-vehicle system such as a car navigation system, an advanced driver assistance system, and a security system. In addition, the electronic device may include any industrial device.

[0120] In such electronic devices, the reliability of the electronic devices as products is improved due to improvements in both the robustness of the above-mentioned first connector 10 or connector module 1 when holding the connection object 40 and the transmission characteristics in signal transmission.
